Argument names in Elisp Reference vs docstrings

[Juanma Barranquero]

It is consistency between argument names in docstrings vs argument
names in the Emacs Lisp Reference a goal?

For example:

  FUNCTION           EMACS LISP REFERENCE      DOCSTRING
 -----------------  ------------------------  -----------------------
  setplist           symbol plist              symbol newplist
  defcustom          option default doc ...    symbol value doc ...
  defun              name argument-list ...    name arglist ...
  gethash            key table default         key table dflt
  indirect-function  function                  object
  eval-region        start end stream ...      start end printflag ...
  kbd                keyseq-text               keys
  make-frame         alist                     parameters
  split-window       window size horizontal    window size horflag

These were chosen almost at random, I didn't do a search looking for
differences.
